vaporware : Java Glossary
- Software announced before it has even been written. Software mired in extended
beta-test would not usually be termed vaporware. A vendor may announce a product only
to test if there is any market interest, or to spoil the actual product announcement of
a competitor. That might be termed pernicious vapourware.
suggests the term mistware for software in beta test with an
unrealistically optimistic promised release date.
